Tensorflow
From Montana Tech High Performance Computing
TensorFlow is an open source software library for numerical computation using data flow graphs developed by Google. It can be used on both CPU and GPU. On the HPC, the GPU supported version of Tensorflow is installed with Python-3.6.4.
To use it, whether on CPU nodes or GPU nodes, both the Python/3.6.4 and cuda/9.0 modules needs to be loaded:
module load python/3.6.4 cuda/9.0
Since the version is GPU supported, you might see some warnings regarding NVIDIA/cuda when running on CPU-only nodes, as shown below, which should be normal.
